BACKGROUND OF THE INVENTION

The present invention relates to a vessel for paste and cream productsin general, such as cosmetic, pharmaceutical products and the like.

As is known, for delivering cream products are conventionally usedvessels in the form of a tube, made by a lot of different makingmethods, said vessels allowing the product to be delivered by pressingor squeezing, and having, usually, the drawback that they does not allowa full delivery of the product held therein to be carried out.

Other prior solutions provide to use a rigid vessel, in which a pressureejector is included, allowing the product to be properly delivered.

However, such an approach requires a comparatively high effort fordelivering the product.

Because of the above mentioned reason, this solution has not been foundas satisfactory by the user.

Moreover, all the above mentioned prior solutions, have the furtherdrawback that they do not provide a proper thermal protection to theproduct, which, in a lot of cases, can be negatively affected by a hightemperature change.

SUMMARY OF THE INVENTION

Accordingly, the aim of the present invention is to overcome the abovementioned drawbacks, by providing a vessel for paste and cream productsin general, such as cosmetic, pharmaceutical products and the like,allowing to thermally preserving the product held therein, therebypreventing said product from being negatively affected.

Within the scope of the above mentioned aim, a main object of thepresent invention is to provide such a vessel allowing to deliver thepaste or cream product without requiring any large effort, whileallowing the product to be fully used or exhausted.

Another object of the present invention is to provide such a vesselincluding a product delivery hole which is properly protected therebypreventing the product from stagnating in contact with air.

Yet another object of the present invention is to provide such a vesselfor paste product in general, such as cosmetic, pharmaceutical productsand the like, which, owing to its specifically designed construction isvery reliable and safe in operation.

According to one aspect of the present invention, the above mentionedaim and objects, as well as yet other objects, which will become moreapparent hereinafter, are achieved by a vessel for paste products ingeneral, such as cosmetic, pharmaceutical products, and the like, incream form, characterized in that said vessel comprises a vessel outerbody defining a chamber for holding the product to be delivered therein,said chamber being closed, on a side, by a ceiling having a productdelivery hole and, on another side, by an ejecting piston, coupled tosaid vessel outer body, closure means for removably closing said productdelivery hole being moreover provided.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

With reference to the number references of the above mentioned figures,the vessel for paste products in general, such as cosmetic,pharmaceutical and the like products, according to the presentinvention, comprises a vessel outer body, generally indicated by thereference number 1, which defines an inner chamber 2 provided forholding therein the product to be delivered, said chamber being closed,at the top thereof, by a ceiling 3, provided with a central deliveryhole 4 which, advantageously, has a substantially frustum of coneconfiguration.

At the bottom portion of said chamber an ejecting piston, generallyindicated by the reference number 10 is provided, said ejecting pistonbeing coupled to the vessel outer body 1, as it will become moreapparent hereinafter.

The outer body 1 is provided with an outer mantle 6, which practicallydefines a gap 7 encompassing the chamber 2 and providing a thermalbarrier.

Moreover, the outer mantle or shell 6 comprises, toward the open portionthereof, an inner thread 20, therewith engages an outer thread 21,formed on a bottom lip 22 of the ejecting piston.

The latter is provided, at the top thereof, with a bottom element 23encompassed by a sealing gasket 24, operating on the side walls of thechamber 2, thereby providing a tight closure of said chamber.

Moreover, said piston comprises an integral bottom cross wall 25transversely formed through a bottom cavity of said piston (see forexample Fig. 2), which cross wall constitutes a handle element to bedirectly gripped by a user thereby allowing to rotatively drive theejecting piston, upwardly in said chamber thereby gradually ejecting, assaid piston is upwardly rotatively driven, said product held in saidchamber 2 through the hole 4.

The delivery hole 4, in particular, can be advantageously closed byremovable closure means, comprising a lug 30, formed on a closure coverelement 31.

Said closure cover 31 can be mounted above the ceiling 3 and comprises agripping projection or lug 32, diametrically arranged with respect tothe pivot region 33, and at a nail recess 34 defined on the outersurface of the vessel outer body.

Accordingly, with the cover element 31 in a closure condition, the lugor projection 30 will be engaged in the frustum of cone shaped hole 4,thereby providing a perfect tight closure, and preventing the product tobe delivered from contacting air.

Another important aspect of the present invention is that the mentionedgap 7 provides a thermal barrier, allowing the product to be perfectlypreserved.

From the above disclosure it should be apparent that the invention fullyachieves the intended aim and objects.

In particular, the vessel according to the present invention, inaddition to providing a perfect preserving of the product, can be usedin a very simple and easy manner, since the delivery of the product canbe simply obtained by turning the ejecting piston, by exploiting thediametrical wall 25, with a consequent introduction of said ejectingpiston into the chamber 2.

The invention, as disclosed, is susceptible to several modifications andvariations, all of which will come within the scope of the invention.

Moreover, all the constructional details can be replaced by othertechnically equivalent elements.

In practicing the invention, the used materials, as well as thecontingent size and shapes can be any, depending on requirements.
